ELECTRICALLY-PROPELLED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 375,346, dated December 27, 1887.

. 0 Application filed April 1, 1887. Serial No. 233,323. (No model,)

' kers, county of W'estchester, State of New York, have invented certain new and useful Improvements in Electrically-Propelled Vehicles; and I do hereby declare that the following is a full, clear, and true description of the same, and that the same has not been patented or in use in this or any other country to my knowledge.

My improvement consists in so connecting the motor employed to the vehicle that absolute freedom of movement may be obtained while rounding sharp curves,while atthe same time the center of "gravity of the vehicle is maintained at a point much lower than the axles of motor employed. To accomplish this result I make use of a curved girder pivoted upon the motor, the girder bearing the weight of one end of the car, while its curved shape allows the car-floor to be carried much lower than would otherwise be possible in the present ordinary construction when using a motor with any great size of driving-wheels.

Referring to the sketch forming part of this application, and which is a side elevation, partly broken away to show the girder, A is an electromagnetic motor pivoted by means of the king-bolt B to the girder O, the spring D serving to give an elastic vertical support to the girder O and its attached car.

It will be seen that the motor A has freedom of movement in a rotative manner-around the kingbolt B, and thus possesses great ease of movementin rounding curves, while the great diameter of the drivers E E renders possible the employment of high speed with an extremely low center of gravity of the attached vehicle.

Having thus described my invention, what I Wish to secure by Letters Patent is this:

In an electrically-propelled vehicle, the combination of the motor with a car capable of conveying movable bodies, the floor of the car being on a plane lower than the axles of the motor A, and the floor being supported in part by the curved girder O, substantially as shown.

In witness whereof I have hereto set my hand, in the presence of two witnesses, this 24th day of March, 1887.

STEPHEN DUDLEY FIELD.
